To all whom it may comm.-

Be it known that I, AMos H. HAWIEY, a

citizen, of the United States, residing at Norwood, in the county of Hamilton and State of Ohio, have'invented certain new and useful Improvements in Platen Mechanism for Accounting-Machines, of which the following is a specification.

- This invention appertains to accounting machines of thosetypes which are equipped with a platen for facilitating the printing of accounting transactions.

In its general organization the invention involves the provision of novel feeding mechanism for platens of accounting machines, mechanism. which is novel particularly in respect to provisions for direct manipulation of the platen for adjusting the paper properly in relation to the printing type cooperating .with the platen. Additionally, there is provided a novel form of indicator associated with the platen in such a manner as to advise the operator visually or audibly, or in both ways, as to the amount of movement which may predeterminately be given to the platen to advance the paper the required amount for, a particular operaiii? tionor operations. Thefeature just mentioned is useful especially in order to call attention of the operator to the fact that the bottom portion of a sheet ofpapor on which tabulations are being performed has been reached.

Ancillary to the indicator construction just referred to, the improvements hereof comprise an especiallyadvantageous means for direct manual restorationof the indicator to a normai or zero position, mechanism which is useful primarily to quickly normalize the indicator when the complete predetermined amount of movement of the platen for which the indicator may happen to'bc set, is decided uponns not necessary to be performed at the particular time.

As an incident to the development of the several features or mechanisms above referred to as essential parts of this invention, a special object in viow has boon the produc tion of means combining the constructional features set forth, .which means is (specially compact in construpfion so as to conduce to the economy of space takcn up thercby, and the employment of the fewest number, of parts possible, all of which is an ever present dcsideratum in the art ,of accounting machines, a

Figs. 11, 12 and 13 are respectively end, top plan. and scctional views, showing the paper dctouts cooperative withthe platen and the controlling means for said device.

The platen mechanism embodying the present improvcmcnts is illustrated in connection with the paper carriage of the International adding machine. As seen best in Figs. 1 to 3 of the drawings. thc carriage A compriscs the side frames 1903 and slides on suitable bearings 2083 disposed in races provided in the upper and lower portions of a race plate 1901 on the carriage A, and corrospmidiug races" in a race plate 190;! wvhicli is fixedly mounted upon the back plate of the adding machine, the latter not illustrated. The mounting of the carriage 1s seen best in Fig. 3, the platen zeal; being mounted upon a main shaft 2095 supported by hearings in the side frames 1903 aforesaid.

Since the construction and arrangement of the parts of the carriage is not; material to this invention, it may be briefly noted that the platen 2096' is o 'ierated by means of a link 7-15 seen best in Figs. 1 to 3, which link 745 is connectedlo an arm 715 in such a manner that when the link H5 is actuated as an incident to operation of the main shaft of the adding machine the arm 715 will rock the shaft 2081. therehy rocking an arm 1907 rotatable with the shaft 2 h]. The arm 1907 has adjustable connection with the actuating link 1908. the latter in turp oper ating the feed pawl 1923 which acts upon the line spacing or ratchet wheel 1921. The manner in .which motion is comn'uinicated from the ratchet wheel 1924 to the platen involves features of construction forming a part of the invention as will now he set forth.

' Connections for worm/ll yflr/fcu fem] III/H027.

Referring partieularly to Fig. 4. it will he observed that the platen 2096 is fixed to its shaft 2095 by means of a set screw 3 and the shaft 2095 is supported hy the right side frames 1903 of the carriage by being mounted directly in the bearing sleeve 4, the latter being free to revolve in the side frame as well as about the shaft 2095 itself. The ratchet wheel 1924 is rigid on the sleeve 4 at the inner end of the latter, and at the inner Side of the adjacent side frame 1903. Fixed to the other or outer end of the sleeve 4 is a tappet wheel 5 provided on its periphery as seen best in Fig. 8, with peripheral tappets or teeth 5, the number of which corresponds with the number of the teeth of the driving ratchet wheel 1924. The tappet wheel 5 is designed to perform a douhle function comprising an element of the connection intermediate the driving ratchet 1924 and the platen shaft 2095, and additionally forming an actuating device for the indicator as will he later set forth.

Describing the functioning of the member 5 as an element of the driving cormeetion above mentioned, it maybe, noted that the tappct wheel is formed with a plurality; of holes arranged in a circular path adjacent to the teeth 5, and at the outer side of the wheel 5 is disposed a pin carrier in the form of a disk 10. The carrierlt) is equipped with a plurality of pins 8 of a numher exceeding by one the numher of the holes or openings in the tappet wheel Said disk 10 is rigidly mounted on a huh 11 supported by the shaft. 2095 and said huh 11 has fixed thereto by means'of a colla" 12 a spider comprising a plurality of radiating spring fingers 9, one finger for each of the pins 8. The lingers U are so disposed that at their outer ends they hear against the outer ends or heads of the. ])lll S and thereby tend to force these pinsinto those of the open ings or holes in the tappet wheel 5 which happen to he positioned opposite the pins ()wing to the relative number of said holes, and the pins 8. it is obvious that there will always he one pin of the carrier 10 which. willhe positioned so that it can enter a hole in the wheel 5. and owing to this condition the resilient fingers 9 are made neces sary, those of these fingers whose pins are not opposite holes in the wheel 5 being capahle of yielding when an imperforate portion of the wheel 5 is opposite the eooperating pin of the same, as will be readily ohvious.

The huh 11 is providcd with a feather or key way adapted to receive a long longi tudinally slidahle key 13 which is disposed .ina hey-way formed lengthwise of the shaft 2095 and in this manner the huh ,1]. is listed for rotation with said shaft, the formation of the key 13, however, permitting of slight longitudinal movement of the hub relatively to the shaft for a purpose to be shortly descrihed.

The foregoing described arrangement and construction of the parts affords a positive driving connection intermediate the ratchet 1924 and the shaft 2095, the turning movement of the ratchet being initially connnunieated to the huh 4 thereby rotating he tappet wheel 5 and the tappet wheel 5 eing interengaged with the pin carrier 10 causes simultaneous turning of the latter. The pin carrier heing keyed or fixed for rotation with the shaft 2095 will normally cause the motion eonnuunicated to the ratchet wheel 1924 to he imparted to the shaft 2095, therehy correspondingly rotating the platen 20% secured 'to said shaft. Any step by step movement imparted to the ratchet wheel while the said driving connection is established will be imparted' to the platen.

Manual adjuntnumt of platen for type alimment.

At the extren'ie outer end of the shaft 2095, see Fig. 4, is located the knob 2066, said knoh being secured by a cross pin 14 to the ke' 13, through which the cross pin passes. t its innermost end the key 13 has a radial projection engaging a shoulder formed by an annular internal groove at the inner end ofthe sleeve 11. Normally the sleeve 11 is maintained in a position wlzerein the parts 5 and 8 are interengaged, owing to the provision of a coiled spring 15 which hears endwise against the outer end of the sleeve.

\Vith the above construction of parts in mind, it will be evident that it is possible a is till

for the operator to pull outwardly upon the knob 2066 and thus cause the projection at the inner end of the key 13 to engage and pull. outward on the hub 11, compressing the spring 15. By this action the several pins 8 are movable sufficiently to disengage the same from the tappet wheel 5, whereupon the platen 2096 is susceptible of being rotated freel y by turning of the knob 2066 and thus imparting corresponding i'novement to the shaft 20%. When freely rotatable by snob 2 366 the above manner it will be ent that the platen 2096 is susceptible of being adjusted readily for purposes of dining indicia on paper passing about the platen withthe type of the type carriers, wli type upon the platen in the usua n'ia i. stment of the platen in the above r or be utilized for any esired purpose where such adjustment is desirable, to facilitate a proper printing action of t pe cooperating with. the oi. respect to the strip of between the platen and ii oistoi'nary impression opapparent. when the desired adjw-tment oi? plate n 2090 has been obtained the ltnob 2066 may be released and .will force the hub 11 to its position and efi ect interlocking of we wheel. 5 and the pin carrier 10 no what the degree of relative movelldtSiJ parts may be as incident to 'g'nlngr the platen in the adjusting operation described. The capability of obthe storing i normal taining the prompt interengagemeut of the l the tapgct wheel 5 is etl'ectnated dispr portion in the relative t the bins 8 and the holes 5-of there is al ys one pin 8 ready to engage in selected one oi the holes 5 even though the remaining; pins are detained from such 1 engagement by non-registration of holes adjacent to the same. The foregoing is clearly illustrated in l 10 of the drawings and affords a construction in which an exceedingly wide range ot fractional adjustments of the parts and 10' is obtainable without preventing the interlocking of these parts once the desired adjustment of the platen 2%?) has been secured.

The reducing drive year Jay for indicator.

As before promised, I contemplate the enq'gloymcnt of an indicator in association- This proportion is such that .ated.

stoppage of printing, at least for the time being, is desired.

Owing to the particular form of the platen and customary considerations appermining to thisparticular art of accounting machines, especially the consideration of economy of space, it is obviously desirable that any indicating means employed shall be compact and susceptible of quick, ready restoration normally. \Vith these factors in view, I employ an indicator which is adapted to be driven directly from the feed ratchet wheel 1924 of the platen and I am enabled to make my indicator comparatively small yet capable of accounting for the maximum requirements so far as number of feed movements indicated by it are concerned, by the utilization of a reducing drive gearing intermediate the ratchet 24 or parts actuated thereby, and the indicator proper.

It has been previously suggested that the wheel 5 is formed withthe tappets 5 and has a oeculiar formation so that it ma r croject outward from the side frame 1903 into the casing which forms the indicator 1, are seen best in Figs. 5 to 8 inclusive. Since the tappet wheel 5' given an increment of movement each time an increment of feeding' movement is imparted to the ratchet wheel 1924:, it is obvious that the wheel 5 is capable of causing a rocking: movement of the lever 7 every time the wheel 5 is actu- The said rocking movement of the lever 7 is employed to actuate a feed pawl 19 which is supported by a stud 20 rigid on the lever 7, said feed pawl being formed with a plurality of teeth engageable with an auxiliary ratchet Whecl 21. The tappot pin 6 of the lever 7 is bold in contact with the tappets or teeth 5 of the wheel 5 by a spring 18, see Fig. 8,said spring being secured at one end to a stud carried by the lever 7 and the other end of the spring being secured to a stud 19' projecting, from the pawl 19.

The auxiliary ratchet wheel 21 is preferably provided with twenty-five teeth and is mounted rotativcly upon a sleeve 22, said sleeve bein; fixed to the shaft 2095 by the pin connection 22. At one side the ratchet wheel 21 has riveted or otherwise secured thereto a cup-shapedspring clutch driving" member 23 and on its opposite side there is similarly secured to the wheel 21 a cupshaped toothed detcnt member 24. The dctcnt member 24 is somewhat larger than the member 23 and the parts 21, 23 and 24;

Mid

eration of the ratchet wheel 1924. Owing to the provision on the pawl 19 of four finely spaced feeding teeth 19", the distance between which is equal to one-fonrth of the distance between the teeth of the auxiliar ratchet wheel 21, it is obvious that a single actuation of the pawl 19 will be snllicient only to turn the ratchet wheel 21 a distance equal to one-fourth of the distance between two of the regularly spaced teeth of said ratchet wheel. Fourv actuations of the lever '7, therefore, are required in ordento rotate the ratchet wheel 2] a distance equivalent to the space between two teeth of said wheel, and owing to this redueing'driving connection it. will be evident that one hundred increments of movement of the platen will have to be imparted thereto in order to turn the ratchet wheel 21 a single complete revolution, there beinr, approximately 27 teeth on the platen feed ratchet Wheel 1924.

The indicator.

The indicator is designated 1, as before mentioned. and comprises virtually a casing which advantageously utilized in my invcntion to house practically all of the various operating parts that have been heretofore described, excepting the ratchet wheel 1924-, the knob 2066, and perhaps one or two other members. has the indicator 1 rigidly secured thereto and also fixed to said hub adjacentto the outer end of the indicator is the detent clutch member 26 formed with teeth correspending with and adapted to engage the peripheral teeth of the clutch member 24 previously mentioned. The teeth of the parts 234 and 9.6 are of a number equ' alent to the number of external graduations which, as seen in Fig. 4, are provided on the exterior of the casing 1. said graduations beinc, adapted to indicate the number of movements which are to be given to the platen when performing a designated operation in the. use of the invention, as for instance the printing of a certain number of items on a sheet or tape fed forward by the platen. There will be provided at a suitable place on the side frame 1903. as shown in Fig. 4, an indicating" pointer 28 opposite which the zero designation oi the graduations of the indicator 1 may be caused to be positioned, and when in such position the indicator is restored or at normal ready to be adjusted to start its indicating operation for the work in hand.

The purpose in providing: the detent clutch members 21 and 26 is to permit the indicator to be initially setfor a particular number of increments of movement in order to perform its visual and audible indicating i'unctions. Supposing, therefore,

.a spring 27 A hub 25011 the shaft 2095,

. considerable distance. The engaged.

that it is desired to print a certain number of items on the sheet ,or tape passing; around the platen 2096, as an incident to which eighty increments of movement must be imparted to the platen. To set the indicator properly for such operation the o nzralor will take hold of the outer klillllcd portion 1 of the indicator, pull outwardly upon the same as seen in Fig. l. and then turn the indicator until the number till opposite the graduations thereon isoppositeto ihc indi eating, pointer previons y refer-rial to. The outward pull on the irnlicator 1 causes emraging the hub to be compressed, the detent clutch member 26 being at the same time disengaged from its oppos.

eration is now ready to be opcm ed intcr-- 9O mittently through the action 01 3 ratchet 1,024. the movement of which is communicated through the parts 5, 5, '7" and .it the ratchet wheel 21. The ratchet eel by the intermittent actuation ot the c act wheel 1924 will be turned in the proper di rcction to gradually restore the mdicator to its zero position.

Of course as soon as the indicatcncs its zero position the condition T nially we made known to the operator thatv the dosired number of movements of" the platen, eighty in the present. instance, have be -n. performed and the particular or "uion referred to is thus made known c z tor as practically completed. In order to insure that the operator may be advised of the coiulition'stated, however, it is preferred to utilize an audible signal.

The mama sign/t1.

The audible signalin means incint. a. projection 1 located teriorly or ing or indicator 1 and so arranm the indicator reaches its Zero ]Iu projection engagcsa pawl member 5531 o; ried by a clapper member 33. The clapper member 33 is nivotally mounted on a. stud 82 carried by the bracket 1.7 which it wil. remembered projects into the indicator 3.

tween the projection l and the pin suthcient to trip the clapper member 36 a thereby cause the latter to engage with the indicator, the latter acting as a sort of bell we in order to perform the function of an audi-- ble signal.

Manuel release meant: for indicator. Under certain conditions it will be evident Mm 1,295,36'7 I men that it may be desired to restore the indicator 1 to its zero position quickly, notwithstanding that the number'of increments of movement to be imparted from the ratchet 5 ,Wheel 19%, and necessary to zeroize the indicator owing to the setting thereof, have not been performed. An instance of thissort arises where items which are being listed run out in the middle of a page and previous, of course, to the restoring of the indicator through the action of the platen drive mechanism. \Vith a view to facilitating restoration of the indicator under conditions such as just stated, I utilize a restoring device which includes primarily the 7 spring or slippage clutch member 23. It will be recalled that the member "23 is fixed to the ratchet wheel 21 and between the periphery of the member 23- and the hub flange 17 of the bracket 17 is located the helical spring 30, the inner end of which is fixed to said hub flange 17 and the outer end of which has a slippage or frictional engagement with the inner surface of the 25 part 23. The functioning of the spring is such that it tends to turn the member 23 and all parts which may be connected or engaged therewith directly or "indirectly, such as the ratchet wheel 21, the clutch parts 30 24c and 26 and the indicator 1, etc., to a position wherein the indicator 1 is at zero adjustment. As the ratchet wheel 21 is turned during the operation of the indicator 1 from the main ratchet wheel 1924, the correspondingmovement of the member 23 has a tendency to cause winding up or reduction of the diameter of the spring 30. Such winding up action continues until the resetting tendency of the spring causes slippage of its outer end in respect to the member 23. With the above arrangement and coiiperation of parts in mind it will be observed from Figs.

4, (S and 7 particularly that I provide a handle 2 extending radially from the indicator 1 adjacent to its inner open end. Said handle 2 is a part of a cam member 2* supported on the hub flange 17 of the bracket 17 for rotative movement, and having pin and slot connections as shown at 2* with said brackets. The cam member 2 is provided with cams 2' adapted to operate against studs 19 and 29* '"hich project from the feed pawl 19 and the detent pawl 29, respectively, which coact with the auxiliary ratchet wheel 21. It will be evident that by slightly pressing against the handle 2 and thereby turning the cam member 2 the cams 2 will elevate the pawls 19 and 29 sufticiently to disengage these pawls from the ratchet wheel 50 21. When the ratchet wheel '21 is disengaged from the pawls l9 and 29, said ratchet Wheel becomes subject to the action of the restoring spring 30 which operates on the member 23 in the manner previously de- #6 scribed. The release of the ratchet wheel 21 I opening of the connecting wheel, and a con REE therefore permits the spring 30 to move the parts 23, 21, 26, 2t and l'to a zero position. The zero position obtained by the release action aforesaid is determined by the pro vision on the outer periphery of the member of a stop 123, seen best in Fig. 6, said stop being adapted to engage with a pawl 31 pivoted to the bracket 17 and seen best also in Fig. 6.
